how can I remove more than one character from a list?

Question

I have a list (new in this, not know how to call it) and want to remove some characters from it but for some reason the function replace() pops a TypeError: 'NoneType' object is not callable

lists = <div class="d-map" itemprop="geo" itemscope="" itemtype="http://schema.org/GeoCoordinates"><meta content="29.028856" itemprop="latitude"/><meta content="-110.955923" itemprop="longitude"/><div id="map" style="height: 230px;"></div></div>

char_remove = ["<", ">","[", "]", "=", ":", "/" ]
for char in char_remove:
    list = lists.replace(char, " ")

You are replacing in `lists`, and returing in `list`. Only the _last_ replacement gets retained. — B Remmelzwaal, Mar 08 '23 at 15:41
Don't use `list` as a variable name, it's the name of a built-in type. — Barmar, Mar 08 '23 at 15:53
Your code is wrong, but I don't see how it could be causing the error you show. Nothiing here does `lists.replace = None` — Barmar, Mar 08 '23 at 15:53

I would recommend RegEx for such a case because it can do the same without the need for a loop.

import re


lists = '<div class="d-map" itemprop="geo" itemscope="" itemtype="http://schema.org/GeoCoordinates"><meta content="29.028856" itemprop="latitude"/><meta content="-110.955923" itemprop="longitude"/><div id="map" style="height: 230px;"></div></div>'

result = re.sub(r'[<>\[\]=:\/]', '', lists)

Result:

'div class"d-map" itemprop"geo" itemscope"" itemtype"httpschema.orgGeoCoordinates"meta content"29.028856" itemprop"latitude"meta content"-110.955923" itemprop"longitude"div id"map" style"height 230px;"divdiv'

Assuming your variable lists (not a great name in this context) is a string then:

lists = """lists = <div class="d-map" itemprop="geo" itemscope="" itemtype="http://schema.org/GeoCoordinates"><meta content="29.028856" itemprop="latitude"/><meta content="-110.955923" itemprop="longitude"/><div id="map" style="height: 230px;"></div></div>"""

char_remove = set('<>[]=:/') # the characters that we don't want

print(''.join(c for c in lists if c not in char_remove))

how can I remove more than one character from a list?
